About Gymnophthalmus underwoodi

Gymnophthalmus underwoodi, commonly referred to as Underwood's spectacled tegu, is a species of lizard belonging to the microteiid family. This species is notable for its unisexual nature, reproducing exclusively through parthenogenesis, a form of asexual reproduction where offspring develop from unfertilized eggs. This reproductive strategy allows the species to propagate without the need for a male.

Distribution and Habitat

The geographic range of Gymnophthalmus underwoodi is extensive, encompassing both South America and a significant number of Caribbean islands. In South America, it has been documented in Guyana, Suriname, Colombia, and Venezuela, with potential presence in Brazil and French Guiana. Its Caribbean distribution includes islands such as the Dominican Republic, Dominica, Antigua and Barbuda, Barbados, Cuba, Guadeloupe, Martinique, Saint Martin, Trinidad and Tobago, the US Virgin Islands (specifically Saint Thomas), Saint Vincent and the Grenadines, Grenada, Sint Eustatius, and Saba. The natural habitat favored by Gymnophthalmus underwoodi is grassland, where it likely finds suitable conditions for foraging and shelter.

Reproduction

As a unisexual species, Gymnophthalmus underwoodi reproduces through parthenogenesis. In captive settings, individuals have been observed laying eggs, with clutch sizes typically ranging from one to four eggs. Over a period of four months, a single specimen has been recorded as laying up to eleven eggs, indicating a capacity for multiple reproductive events within a relatively short timeframe.

Etymology

The species was first described by Chapman Grant in 1958. The specific epithet, 'underwoodi,' was chosen by Grant to honor the British herpetologist Garth Underwood. This dedication recognizes Underwood's significant contributions to the study of West Indian reptiles. Underwood himself had collected specimens from Barbados in 1958, which were initially classified as Gymnophthalmus lineatus but later became designated as paratypes by Grant during his investigation into this potentially new species.
